after updating OH2-Online (Nightly) via apt-get I lost all my things and items. All of these are configured in the database. Bindings and addons are defined in the addons.cfg, and were properly reinstalled, but the things/items did not show up again. Hence, I had to reinstall and configure everything again.
Restoring a backup did not help. The things/items have shown up again with errors, but after a reboot they disappeared and the database seemed to be empty again.
Is this a known issue? It happened to me for the second time. I was searching for a guide to do a “safe” update, but haven’t found anything.
I am happy for any tip so I can still update from time to time.
